my six years old son is very adamant and he doesn't listen to us. till last year he studied well, but from this year his studied capacity will getting less, his class teacher complains me that he would not listen to the class while they are taking lessons and also he finished his writing his class work while they write in the board. if they asked him to standup or asked any questions he doesn't answer to them. they told me, he is abnormal,pls get him to therapy class. even in the home he doesn't listen our words, he simply sitting or he doesn't bother our words, i'm very worried about my son, i don't know how to handle this situation. shall i take him to any therapy class or to consult a doctor. if we take him to therapy, is he changed his activities or not. kindly advise.
